Introduction

Founded in 1709, Trinity School has an established reputation of academic excellence and deep roots in New York City. In 2023, Trinity was ranked the 14th most sought-after school, and was the 3rd most sought-after school in New York City. 

Trinity has many great offerings and opportunities for students, so it draws a large applicant pool each year. It can feel intimidating to apply to such a competitive school, so we’ve created this guide to help you understand and prepare for the application process. 

We recommend using this guide in conjunction with the Test Innovators Admissions Assist courses. Our courses will help you understand what schools are looking for, give you the tools to write your strongest application essay, and prepare for your admissions interview.

Admissions Interview

After applying, families may be contacted by the Trinity admissions office to schedule interviews or additional visits, depending on the grade level and availability. Trinity has a limited number of interview opportunities, and the process varies between Kindergarten, Grade 9, and applicants to other grades. Families are encouraged to submit their applications early and refer to Trinity’s admissions website for the specific interview requirements for their child’s grade.

The interview is a great chance for you to make a positive impression and demonstrate why you are a good fit for Trinity. It is an exciting part of the application process, but preparation is important to ensure you put your best foot forward. At Test Innovators, we have created an Interview Prep course to help students and parents build skills to ace the interview. Our course will help you tell your story, prepare for common interview questions, and gain interview confidence.

Along with our Admissions Assist courses, we also recommend researching Trinity and preparing to share why you are applying. Read their mission statement and see what life is like at Trinity’s lower school or upper school. Look at their academics page, and read about the curriculum for your grade level. See their athletics programs or arts programs, and consider what you would like to get involved in as a student. If there are specific offerings that you are excited about, your interview is a great chance to share these with the school. 

Admissions Tests

The following tests are required for each grade level:

  • Kindergarten: Developmentally appropriate child assessment.
  • Grades 2–4: ISEE Primary.
  • Grade 9: ISEE or SSAT.
  • Other grades: Requirements vary depending on the grade and whether an opening is available.

Preparing for the ISEE or SSAT will help you understand the test and gain confidence for test day. Test Innovators is an official practice partner for the SSAT and is the only ISEE prep officially endorsed by ERB.

Our platform offers full-length practice tests with detailed scoring and analysis. You can compare your practice test scores to target scores for Trinity and other schools. You will also get feedback on your timing and results by subtype, as well as personalized suggestions for what to work on next.
